PRESSURE FOUNTAIN-PUMP.

SPECIFICATION forming part of Letters Patent No. 241,621, dated May 1'7,1881.

Application filed February 8,1881. (No model.)

To all whom it may concern:

Be it known that I, MONTRAVILLE COOPER, acitizen of the United States,residing at Golumbia, in the county of Richland and State of SouthOarolina,have invented certain new and useful Improvements in PressureFountain- Pumps; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanyin g drawings, and to theletters or figures of reference marked thereon, which form apart of thisspecification. I

This invention has relation to improvements in force-pumps or hydraulicapparatus for raising water. I a

The object of my invention is to provide a means for raising water froma well, cistern, or other body of water in a large or small volume, asmay be desired, the flow being regulated by the size of the reservoirused and the hollow plunger, through which the water is forced, and bythe weight of the plunger; and it consists in the construction and novelarrangement of parts, as hereinafter shown, described, and particularlypointed out in the claims.

In the annexed drawings, Figure 1 is a sectional elevation. Fig. 2 is aview of the operating mechanism with the hollow ratcheted plunger-rodattached.

In the accompanying drawings, the letter A represents the air-tightreservoir, made round or square, and wholly or partially of metal.

The letter B designates the inlet-opening in the side of the reservoir,near the bottom, for the purpose of admitting water into the saidreservoir. This inlet is opened and closed by a slide, 0, working inways a, attached to the side of the reservoir near the top and bottomportion thereof.

The letter D indicates the weighted plunger, fitting snugly and workingon the inner walls of the reservoir, and having a central opening, z.

E represents the hollow toothed plunger-rod passed into the said openingof the plunger. This hollow plunger-rod is provided at or near its topportion with a stop-cock, f, for the purpose of increasing or decreasingthe flow of water from said rod.

The letters F F designate two platforms mounted upon legs, and placed asuitable distance apart to admit between them the plunger-rod E, whichenables it to move the plunger up and down in the reservoir. Upon thesetwo platforms bearings 7c are secured for the reception of a shafthaving a master-wheel, I. This shaft is also provided with a pinion, K,engaging the teeth I) on the face of the plunger-rod. by a crank-wheel,J, which imparts motion to the pinion K and moves the plunger up ordown. The platform F is provided with an upright, L, having a lever, L,pivoted thereto. The far end of the lever is hinged to a perforation, m,inthe slide to open and close the inlet B. A spring-pawl, c, is alsosecured to the platform F, which engages the ratchets d at the side ofthe plunger-rod E to secure itin place.

The operation of my invention is as follows: The reservoir is solidlyand securely placed in the bottom of a well, cistern, or other body ofwater. The slide is then drawn upward by the lever to admit waterthrough the inlet into the reservoir, and then the weighted plunger,with its hollow ratcheted plunger-rod, is raised in said reservoir bymeans of the mechanism described. When the reservoir is sufficientlyfull the slide is let down by the lever, thus closin g said inlet. Whenthis is accomplished the hollow rod descends, and the water is forcedupward through said rod by the downward pressure of the weightedplunger.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination, with the reservoir A, having the inlet B in its sidenear the bottom, and provided with the slide 0, having the lever L toopen and close said slide, of the weighted plunger D, having the hollowplunger-rod E, operated by a suitable mechanism, as shown and described.
